我得到了解决方案，这是因为我错误地实现了我的gradle文件，我不知道如何在Kotlin中添加依赖关系，所以我学习了它，并做了一些这样的改变，它解决了我的问题：-

plugins {
    id("com.android.application")
    id("org.jetbrains.kotlin.android")
    kotlin("kapt")
    id("com.google.dagger.hilt.android")
}

//Dagger - Hilt
    kapt ("androidx.hilt:hilt-compiler:1.0.0")
    implementation ("androidx.hilt:hilt-navigation-compose:1.0.0")
    implementation("com.google.dagger:hilt-android:2.44")
    kapt("com.google.dagger:hilt-android-compiler:2.44")

字符串
我的build.gradle（app模块）：-

plugins {
    id("com.android.application") version "8.1.0" apply false
    id("org.jetbrains.kotlin.android") version "1.8.10" apply false
    id("com.google.dagger.hilt.android") version "2.44" apply false
}

我还得到了另一个错误，我必须将我的jvm版本从1.8更改为jvm 17：

compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
    kotlinOptions {
        jvmTarget = "17"
    }

在您的AndroidManifest.xml中，您已经声明了一个

<application
    android:name=".MainApp"

字符串
您需要拥有（或创建）一个扩展android.app.Application的类com.sleepmagic.MainApp。
或者干脆把线去掉。
